Suppose that X is a random variable for which the p. d.f. or the p. f. is f(x|e), where the value of the parameter 6 is unknown
but must lie in an open interval 9 Let IO(e) denote the Fisher information in X Suppose now that the parameter 6 is
replaced by a new parameter u, where e = Wu). and q: is a differentiable function. Let |1[u) denote the Fisher information
in X when the parameter is regarded as u. Show that

|1(IJ) = [w'(u)]2|0[w(u)].

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

my guess is

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
